No; 722,634, granted. me March 10, 1903, for.

presser-pla'te on the" plunger-headwhich is held by spring-pressure uponi-a usual neck-- mold while' the plunger is beingreleased vfromthe pressed. blank, the presser-plate upon such release following the plunger in its upward mo'vement A mechanism of this Letters ,Patent' glass blowing machine. Machines of this.

character have been used in: which a-m11l-.-

tiple ofsprings' have been employedto exert pressureupon. the presser plate, sometimestwo, at other times three or .four, or any numberthat might be desired, 'Oneof the objections to mechanism of this charac ter has been the difliculty of maintaining" the springs of a given plunger-head at equal elastic stren h,'result1ng in difierent pressures at' di erent points of the presserplate. Another-objection .has been the annoyance 'occasionedby'the brealnng otthe springs and the'difliculty offindlng springs having elastic strength similar to those al .readyupon the head, and the loss of time occaslonedby changing springs, these iditficulties being enhanced byv the fact that 1n operation the springs are subjected'to heat and areliable to lose elasticity or strength; in consequence. f It is the object of my invention to avoid these difiicult'ies an l to provide a device that man facturing-glassware in which the glass {latter-t 1 r in amac'hine which embodies a-press-mold will dispense u .311 the necessity of 1 have shown' this accompli springs" for the purpose mentioned, and to provide a device in which. the pressure upon' the presser-part may be maintained uniform throughoutthe presser'-part.

1 represents a press-moldtable is" j ournale'd about a column-'2, the table having thereon a-suitablenumber of press-molds,

one ofwhich isshownat 3.- The press-molds :are arranged. ,to be alternately positioned under. a g l'un ger .4 in usual manner.v 1 p I 5 indicates a' blow-mold table adapted to 9 rotate in unisonv with the table-lander 7 5, derstood from the following description and rod 6 which acts on the plunger for reciprocating the same, the rod having connection with a plston 7 operating in acylinder 8 in usual manner. This operation may be accomplished by compressed air' received through a feed-pipe 9 and through pipes 10 11 connectingwith the interior of the cylinder 8 at the respective sides of its pistong a controllin valve 12 for the same being provided, w ich is manipulated by an operating-lever 13. v

14 represents a suitable mold-shown as a separable neckanold of usual construction,

which is arranged to be placed-upon the press mold 3, and is provided with suitable suspending means for the pressed glassblank, shown at 15, hese suspending means necleendot. the fruit-jar;

1 being for instance the threads 16 at the I7 isa presser-plate which may have a presser-ring' '18suitably secured thereto and arranged to contact the neck-mold fupon descent of the plunger for confining the molten glass which has been introduced intothe press-mold; the shank of the plunger fitting the central aperture of said presserring. Y

.T-hereis an elastic-fluid cushioning device interposed between the operating rod G and the press-mold which comprlsesa' cylmder 19 and. a piston 20 therefor one.

of said parts being connected with the plunger and the other with the p'resser plate. Thus the plunger 4 is suitably secured to the cushionrylinder 19 as by being fastened to a flange 21 thereon by means of bolts 22. The plunger may be provided with a cavity 23 which is coincident in position with a cavity 24 in the cylinder 19 and has an inlet-pipe 25 and an outlet-pipe 26, communicating with said cavity for the purpose of providing circulation-of a cooling agency in said cavity, for-instance water in order to maintain the plunger at proper temperature 'for acting upon the molten glass.

The cushion-piston 20 is shown as pro vided with expansion-rings 20 and connects with the presser-plate 1-7 in suitable manner, as by means of rods 27 preferably rigidlysecurcd to the piston and to the presser-plate the resser-plate being preferably prevented from turning as by passing said rods through bearings 8 in lugs 29 0f the cylinder 19. Tl18" C Vl111ClQl 19 is prevented from turning by a rod 30 secured to i said cylinder and slidable in a bearing 31 11511111 COllStl'll 011.

32 is a litt-out ttor lifting the pressed blank out of the press-mold and may be of T have shown thesame as comprising a voae 33 on lwhich trips 34 are pivoted on bolts 35, the trips being arranged to be received under lugs 36 at the respective sides of the neck-mold The yoke is secured to a piston rod 37. having a piston 38 attached thereto which reciprocates in a cylinder 39, a branch-pipe 4O connecting the-pipe 10 with one end of the cylinder 39 and a branch-pipe 41 connectcylinder, a rod 42 secured to the yoke and sliding in a bearing 43 preventing said yoke from turning. Movement of the operating lever 13 in'one direction will cause descent of the'plun'ger and lift-out,- and movement tion will cause ascent'of said plunger followed by ascent of said lift-out, as more .fully shown and described in Letters Patent Nos. 855,344 and 855,345, granted me May "as, 1907,

ceived in the press-mold in usual manner, the neck-mold being placed on the press- I mold, when by manipulation .of the operating' lever 13, the controlling valvel2 is turned for admittin compressedair above press-mold; .lVhenthe presser-ringflfi en gages the neck-mold, (the presser-plate'iwill pisto'n'20 and the compression of the air in the cylinder 19,. this pressure being great the plunger 4, and definitely positioning the resser-parts upon the neck-mold and actgel 4 passing through the presser-plate into theblank of molten glass for shaping the ,tarded descent of said cushion-piston, As shown, the valve 44 comprlses a valve-seat stem 47 passing through a cup 48 secured tothe head 49 on the cylinder 19, the stem having a spring 50 thereabout, the tension of which may be regulated by a nut 51, air-passages 52 being provided in said cup and communicating. with the interior of the cylinder 19.-

i'ng the pipe 11 with the other end of said of said operating lever in the other direc-- A suitable blank of molten glass, is re-'.

The Presser-ring continesthe molten glass within the press-mold and" the elhsticv fluid compressed within the cushion-cylina der aids in recession of the plunger as soon Pressure-regulating means are provided? be arrested, causing arrestof the cushion said valve for causing a prompt orrer 45 in thecylin'der, a valve-proper 46 on af for said elastic-fluid cushioning means.

is, a pistont'onthe auxiliiirycvlinder arranged to be positioned therein for increas- --ing or decreasing the cushion-space upon which the main cushion-piston acts. It i hown as P1.0\ l(l8(l \vith expansion-rings I he positioning-of this piston may be accomplished by iiieans of a screw SShavii' g threaded bearing 59 in the end 60 of said auxiliary cylinder and operated bya handi'egulating the pressure exerted upon the and I regulating this pressure in delicate manner,
